Glossary Term
The probability that a test will produce a true negative result when used on non-effected subjects as compared to a reference or "gold standard". The specificity of a test can be determined by calculating: number of true negative results divided by the sum of true negative results plus number of false positive results.

Glossary Term
A PCR format that partitions each sample into thousands of sub-reactions and calls each partition positive or negative, giving absolute quantification without a standard curve. Useful for low-level targets, copy-number work, and reference material characterization; throughput and per-test cost differ from qPCR.
Pcr Terms
Tests
The determination of the amount of double negative B-lymphocytes present in a sample.
For professionals
Tests
The determination of a sub-population of double negative B-lymphocytes to B-lymphocytes in a biological specimen
For professionals
Tests
The determination of the ratio of double negative B-lymphocytes to B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
